"Frank Anscombe" likely refers to Francis Anscombe, a notable statistician known for his contributions to statistical theory and practice. One of his most famous contributions is Anscombe's quartet, a set of four datasets that have nearly identical simple descriptive statistics (mean, variance, correlation, etc.) but differ significantly when it comes to their distributions and relationships. This work highlights the importance of visualizing data before making statistical inferences, emphasizing that relying solely on summary statistics can be misleading.
